Objective To evaluate estrogen receptors (ERs) α and β expression in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) in China and their relationship with clinical and pathological characteristics. Methods Expression of ERα and ERβ in 28 cases of HBV-related HCC was detected by immunohistochemistry technique EnVision method. ERα and ERβ relationship with the clinical and pathological characteristics of HBV-related HCC was analyz
ed statistically. Results Both ERα and ERβ were expressed in the cytoplasm. The positive expression rate of ERα and ERβ was 35.7% (10/28) and 46.4% (13/28)
respectively. There was correlation between ERα expression and tumor diameter and TNM stage. Higher ERα expression was found in tumor with diameter ≤5 cm than in tumor with diameter >5 cm (60.0%

as well as in tumor with TNM stage Ⅰ to Ⅱ than in tumor with TNM stage Ⅲ to Ⅳ (60.0%
